it's very noticeable... and there's no discomfort in daily driving. easily my 2nd favorite modd right after my interceptor x

Polak & RX Tuner did a writeup several months back where he dynoed a car, did the swap of the flywheel & REVi and got 10 whp. Also Nemesis, has a dyno & writeup on the RP Supercat, got about 6-8 hp.

Will the dealer give you any crap about the act prolite flywheel or rp supercat (warranty)? Considering these 2 are my next mods (excluding body kit) I would like to know before I purchase.

But if you have a lightened flywheel. Say act prolite (8 pounds or so?) Wouldn't that make it easier to stall and harder to get smooth starts because the rpms would rise and fall so much quicker? It's pretty cool its like 50 percent of the stocks weight though

They technically shouldn't give you crap unless it's determined as a possible cause of failure for something. So if you put some flywheel in and it explodes, nothing will be covered under warranty.

Nopstnz

Haha, thanks. Yeah, that would really suck if that happened and it blew through the floor and took off my head or something. But then I guess I wouldn't have an issue with warranty cuz I'd be dead.

flyboi1121

you'd have to rev to like 18k rpm and cut out the floor and then maybe u'll die =P

prolite weighs more than racing beat and a few others cuz you have to add the counterweight.

ddub

There's better springs out there for cheaper than the RB ones, they are pretty mild.

Also, the RB flywheel weights are without the counterweight as well, last time I checked. At least that's how it was on my 2nd gen rx7, weight listed was minus counterweight.

wow never thought about adding up those numbers... this means its actually possible to get over 200+ hp N/A with those mods... pretty interesting!

Fanman

Are you trying to be a jerk, or just coming off as one ? I never said it would get over 200+ whp. You don't just add stuff together & that's the new hp you get. Amateur hour. I said the hi-flow cat adds about 6-8 hp...FACT. I said the flywheel w/ the REVi airbox tested by Polak & RX Tuner got about 10 whp...FACT. Is there a particular reason you are throwing me that sarcastic rolleyes nonsense ? If you got something to contribute then go for it, otherwise stop being a clown.

Fanman

It depends on your dealer. When I brought my car in it is "slightly" modified. The service manager, just laughed a little and did the recall/service. In regards to making it easier to stall & harder to get smooth starts, yes that is true. I have the SR Motorsports unit, and it is those things (slightly).

i thought that the Mazdaspeed flywheel was one of the best flywheels around, it was lighter, with the counter weight added in,whys the ACT prolite getting some much attention? would there be that much of a noticable difference between then ACT and the MS flywheel?
Sorry to hijack the thread, my budget isnt under 1000 Bucks, but ive just started to mod my 8, Got the borla on the way, Agency Power Pullys, and the Axial Flow Short Shifter, my next is the Revi with the Duct, then more then likely the flywheel.. so.. i wanna get as much info as i can

Dyno results on the web sites are crap. You might get half of what they claim. I've dyno'd enough bikes to know that magazines and web sites are nothing but BS. Until I see private dyno results from us guys running our own cars, I won't believe them....

You can play with the correction factor and ambient temperature to make any HP gain at least double the actual difference.

I'm going for ACT as well - from all the reading I've done the only noticable difference with the MS will be the effect on your wallet .

mysql101

Do NOT do this unless you're OK with your car sounding like you strapped on two dozen honda civics with broken cats to the back of your car. It's loud, and it's going to drone like there's no tomorrow.

With a turbo, it sounds pretty good, NA, it's a rice fest.

Fanman

No, the Mazdaspeed is actually one of the heavier ones, but it is a very well made unit, with more of it's weight centered in the middle. In the RX Tuner article, the Unorthodox Racing unit was quite a bit lighter than the MS unit, which was 15.5 lbs (the stock unit weighs 17 lbs.), and the UR unit weight 14 lbs. ACT is lighter so revving up might be a bit faster, but that makes it a bit more finicky.

Fanman

I completely agree with you about taking a boulder of salt on vendor claims on hp gains with their parts. I got into a heated argument with one of the posters here about that a while ago (I say vendor dyno are garbage). But the dyno gains of about 10 hp from the flywheel, & intake were done by a well respected poster on this site, and RX Tuner is about as legit a magazine for RX cars as you have. Also the 6-8 hp gain from the high flow cat was done by Nemesis, another well respected poster on this board. I believe these dynos far more than others as they do not have a financial motive for their results, unlike vendors that want you to buy their products.

flyboi1121

reasons why i got the act prolite are:

1. cheaper
2. one of the lighter ones
3. also designed well with the outter weights removed to help it spin faster
4. did i mention it's cheaper? ^^

zenmoused

What's a good price do you guys think to get a flywheel installed? Just want to know before I get it done

flyboi1121

between $350-400. thats how much i got it for

the first price everyone gave me was between $400-550. i negotiated it down

ddub

Mine isn't too bad. Yah it's loud, but there are civics all around here that are louder than my car... My catless midpipe IS resonated, which helps a very tiny bit, but still it isn't bad.

Obviously you guys haven't had rotaries long enough yet :P

My last car was a 2nd gen rx7, big street port at one point then later a partial bridgeport (aux) with large extend porting on the primary/secondary ports, header, straight pipe, dual partially blown ebay mufflers. Now that's loud... makes something like the rx8 very tolerable and not bad when you've driven that for a couple years.

ddub

What a waste...

Get some tools, a jack, some jack stands, and learn to do stuff yourself people! You'll save lots of money in the long run. Doesn't it seem crappy to any of you that the cost of installing a part is the same as the cost to buy it?

well im sorry if you took that offensively... i didnt say the numbers of those mods were not real... and since most people dynoed at around 175-185 hp stock then the numbers of hp gain from the mods can add up to be possibly around 200. if you add the numbers of hp thats possible from those mods to the stock dynoed hp and dont get around 200 then you can call me nonsense.... and of course i understand not everyone will get those numbers but there are gains. by the way the rolleye was a misunderstanding... it was meant to be wondering........ so just chill

I couldn't agree more man. However my apartment complex tends to frown on people dropping the transmission of their cars in the parking lot. Being in college here, I don't know anybody who has a driveway either :-(

Skiptomylue

i concur with both statments, i love doing work on cars, even if im not the most knowledgable person, i love to work on them, everything im doing to my 8 im going to do (cept The flywheel as of right now and then later FI) but the exhaust, SS, pullies, intake, doing myself, i say everyone should.. taht way if something goes wrong.. you only have YOU to blame.. BUT. Most of us dont have the time, the knowledge, or the tools to do the job them selves, so they take it to the shop.
I wish I had the tools and resorces to do my own work..

ddub

Ah, apartment life. That's more understandable then, I have some friends living in complexs that don't allow them to do work in their parking space, kinda sucks. And I know how college life is too, I'm currently in college also, but luckily I live in a house with a garage/driveway and all my tools.
